Aim: To assess the quality and reliability of video content on Dental Sleep Medicine on YouTube™.
Methods: A search was performed on YouTube™ using the term “Dental Sleep Medicine”. The first 100 videos were selected for analysis by two researchers. Videos on the subject were included, in Brazilian Portuguese with a maximum of 24 minutes. The following data were extracted: title, date, duration, views, likes, source, target audience, objective and subject. Quality was assessed using the Global Quality Scale (GQS), and reliability using a previously published index adapted, both ranging from 1 to 5 points, where more points meant greater quality and reliability. Spearman correlation, Mann-Whitney U, and Kruskal-Wallis test (p < 0.05) were performed.
Results: 58 videos were included, with a median duration of 2.4 ± 7.6 minutes. Most of the videos were produced by dentists (75.9%; n = 44), about apnea (96.6%; n = 56), with an educational/informational objective (65.5%; n =38), and aimed at laypeople (58.6%; n = 34). Most had a low median of 2.0 ± 1.0 on the GQS (41.4%; n = 24), and on the reliability scale, the median was 3.0 ± 1.0 (60.3%; n = 35). There was a moderate correlation between both GQS (ρ = 0.62; p < 0.01) and reliability (ρ = 0.41; p < 0.01) with video duration, and also between GQS and reliability (ρ = 0 .66; p < 0.01). Educational/informational videos, produced by dentists, and aimed at laypeople showed higher GQS and reliability (p < 0.01). Videos that included bruxism had higher GQS (p = 0.01). Television programs and non-commercial videos were more reliable (p < 0.05).
Conclusion: Most videos had low quality and moderate reliability. Educational/informational videos, made by dentists, aimed at laypeople, that included bruxism, television programs, and that were not commercials, presented higher quality and reliability.
